Dated versions never change. ## Query The query API returns only the rows you ask for, as JSON, NDJSON or CSV, from the same typed rows as the files. It needs no key. Rows: https://publicdata.au/api/v1/datasets/nt-crocodile-captures/rows. Counts and sums: https://publicdata.au/api/v1/datasets/nt-crocodile-captures/aggregate. - Rows: https://publicdata.au/api/v1/datasets/nt-crocodile-captures/rows?zone_name=eq.Upper%20Harbour&limit=5 - Aggregate: https://publicdata.au/api/v1/datasets/nt-crocodile-captures/aggregate?group=scientific_name&metric=count&zone_name=eq.Upper%20Harbour Each filter is `field=operator.value` in the query string, and every filter must match. A number or date field compares as a number or date, and a text field compares as text. Values are case-sensitive except with `ilike`. Prefix `not.` to negate a filter, as `not.eq.value`. Operators: `eq.value`, `neq.value`, `gt.value`, `gte.value`, `lt.value`, `lte.value`, `like.*text*`, `ilike.*text*`, `in.(a,b,c)`, `is.null`. - `select`: Fields to return, comma-separated. Every field when absent. - `order`: `field.asc` or `field.desc`, comma-separated. The publisher's row order when absent. - `limit`: Rows per page, 1 to 10,000. 100 when absent. - `offset`: Rows to skip. The `next` URL in each answer sets it for you. - `group`: On `aggregate`, fields to group by, comma-separated. - `metric`: On `aggregate`, `count`, `sum.field`, `avg.field`, `min.field` or `max.field`, comma-separated. `count` when absent. - `format`: `json`, `ndjson` or `csv`. JSON carries the provenance header, and the others carry it in response headers. Without a version the API answers from the newest loaded version, and that answer changes when the publisher releases again. Put `versions//` before `rows` or `aggregate` for an answer that never changes. `/api/v1/datasets//versions` lists the loaded versions. The API allows 60 requests in 10 seconds from one address. Above that it answers 429 for 10 seconds with a `Retry-After` header, a `RateLimit-Policy` header and a JSON body that gives the limit. Every API answer carries the same `RateLimit-Policy`. A client should wait the `Retry-After` seconds, or read the files, which have no limit.

Open https://publicdata.au/d/nt-crocodile-captures/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/nt-crocodile-captures/v/2026-10-04/data.csv today. The same path serves Excel, JSON, Parquet, SQLite, DuckDB, NDJSON, Arrow. A dated URL never changes, so use it when the file must stay the same. ### Can I open Crocodile captures in Excel? Yes. https://publicdata.au/d/nt-crocodile-captures/v/2026-10-04/data.xlsx is a workbook with the 5,632 rows on a records sheet, the field list on a second sheet and the provenance on a third. The CSV also opens in Excel. https://publicdata.au/d/nt-crocodile-captures/v/2026-10-04/data.csv.gz is the CSV at about a tenth of the size. ### What years does Crocodile captures cover? The current version covers 1998 to 2025. Each release from Lands, Planning and Environment becomes a new dated version here, and earlier versions stay online. ### How often is Crocodile captures updated? Lands, Planning and Environment releases it through the year. This site checks the portal every week and adds a dated version when the file changes. ### Can I use Crocodile captures commercially? Yes. CC BY 4.0 allows commercial use, redistribution and derived works as long as the attribution is kept. The attribution string is in this page's side column and inside every file. ### Is this the official source for Crocodile captures? No. The publisher is Department of Lands, Planning and Environment, and its page is https://data.nt.gov.au/dataset/nt-crocodile-capture-zones-and-daily-count. This site republishes the publisher's file without changing its content. The original sits beside every version as source.zip with its SHA-256, so the two can be compared. ### How do I get only the rows for one zone name? Every version has one JSON file per value of zone_name, 10 files in the current version, listed with row counts at https://publicdata.au/d/nt-crocodile-captures/v/2026-10-04/by/zone_name/index.json. For example https://publicdata.au/d/nt-crocodile-captures/v/2026-10-04/by/zone_name/upper-harbour.json holds the 1,410 rows where zone_name is Upper Harbour. ### What is in each row? One crocodile captured, with the date, species, capture method, total length, head length and snout to vent length in centimetres, sex, whether the tail was complete, and the region, capture zone, location group and location where it was caught. ### Where exactly was each crocodile caught? The publisher does not release trap coordinates. Each capture is placed by its zone, a location group such as a river or creek, and a location name. ### How often is it updated? The publisher adds captures to the file through the year. The September 2026 file runs to 30 September 2026. This site checks it weekly and adds a dated version when the file changes. ## What this site did to the data Cells were typed, headers were renamed to snake_case and the encoding was made UTF-8. Rows were left alone. Nothing is derived. The publisher's file is beside every version as `source.zip`. ## Improve this dataset This page is built from [register/nt-crocodile-captures.yaml](https://github.com/National-Digital/publicdata.au/blob/main/register/nt-crocodile-captures.yaml) on GitHub, and a fix to it is welcome as a pull request. https://publicdata.au/contribute/ explains how.
